Application filed `November 18, 1925. Serial No. 69,778.

rlhis invention relates to grain door pullers of the general characterdisclosed in my United tytates Letters Patent issued to me on May 19th,1925 and which has been given Number 1,538,024.

As is well known to the users of devices ot this character, it is mostnecessary to provide a grain door puller which will etectively andpositively engage and grip the grain door which is to be removed withoutbreaking or `otherwise mutilating the same.

It is the prin'iary object of this invention to provide a grain doorpuller which has a portion adapted to engage the grain door at theyinwardly facing side and adjacent the lowerinost edge thereoi", as wellas to provide another v.engaging member which engages the grain door atthe outwardly ,tacing side `and near the top edge of the door.

An even .further object of this invention -is the provision ot a. graindoor puller which may be adjusted to engage either a single or a doublethickness grain door.

A still further object or the instant vinvention is the contemplaton'ol5a grain door 'puller as above set forth which has an adjustable engagingbar provided with a pivotally mounted toot adjacent the pointed endthereof which ymay act as a sar'eguard against the ypossible .splitting`of the grain door when torce is exerted and the pointed endet thelbaris-being driven into the door by this iorce.

Many minor objects will appear during thecoursc of the detailedspecilication which reuters to the accompanying drawingillustratingthe-preferred form of the invention and which lis shown constructed topresent a strong structure, one easy to make, eiective in its operationand not likely to get out ofender.

In `the accompanying drawing:

Figure 1 is a vertical section :through a grain door showing the graindoor puller in side elevation and in position for receiving a lifting`force.

ried by the door-engaging end ofthe adjustable engaging bar.

nWith particular reference -at this time to the drawings in detailwherein similar rei erence characters refer to like parts throughout theseveral views, the numeral 5 designates one of the two door posts of aboX` car against which the well known rgrain-door V6 is ynailedtopreclude `the grain which is loaded into the car from falling againstthe ordinary `car door, not here shown.

it is well known that -the grain door 6 must be forced rinwardly and.lifted before it can be removed from .the position shown in Fig. 1. Theweight ofithegrain bearing against door 6 `requires ythe use of a strongand effective device of .fthe character shown which :is .adapted to gripthe door and receive the lifting power. In its preferred form the graindoor puller should be con- Structedof metal and have a bodymember 7which comprises a y:pair of yspaced apart members angled slightly fromthe `straight line as shown in Fig. 1. Connecting bolts 8 may be EusedIto maintain'the .members oi body 7 in the proper relative position asWellfas to afford an attaching means .for .a

-chainor similar member 9 lwhich kis engaged by rhook 10 actuated tolitt the entire device and y grain vdoor through any suitable connectionto a sourceo power.

Engaging bar 12 is rigidly attached, and

extends downwardly from oneend of body member 7, by a =bolt 13. lBar 12may be rigidly held in positionand.strengthened by link 11i which isbit'urcated at its ylower end to pass `on `either side ot bar '12 to -beat tached thereto by rivet or analogous means 15. The upper end .thereofpasses between the sides of body member 7 `and is rigidly connectedthereto lby a bolt or rivet `16.

Another door engaging bar 17 is carried by body member 7 which passesbetween the members thereof near'fthe endlopposite `from the attachingpoint of engaging bar 12. This adjustable bar 17 is provided with aplurality of holes 1.8 which pass therethrough to register with a holeoi asimilar size formed through-the sidemembers of body 7. In thisinstance but two holes 18ers shown, and the rear one is lbeing used toIhold vbar 17 in a condition -to effectively grip ka single thick- Theneither of the holes in bar 17 registers with the hole in 'body member 7,`a pin 19 may be Vpassed 4therethrough to maintain the same lin rigidassembled relation. This pin 19 may be hung to body member 7 by aflexible chain or the like 20. The forward or door engaging end of bar17 is supported by a link 21 which pivotally inter-connects the same tobody member 7 as shown in Figs. 1 and 3. This link keeps the door-engaging end from dropping down around a center formed by pin 19. Bothengaging bars 12 .and 17 are formed to present spurs 22 and 23respectively, which embed themselves in the sides of the grain door whenit is being pulled from its position. The engaging bar 12 is providedwith a shoulder 24 which precludes spur 22 from digging too deep intothe door 6.

Obviously the greatest force is exerted against grain door 6 whereengaging bar 17 engages the outer sidev thereof. To keep spur 23 fromsplitting or otherwise mutilating the door, a pressure equalizing foot25 is pivotally mounted intermediate its upper and lower sides to bar 17immediately behind spur 23. This foot 25 may be constructed in anysuitable manner such as shown in Fig. 4t, and the door engaging facethereof may be serrated as at 26 if desired.

Operation.

When it is desired to remove a grain door from a car of loaded grain itis but necessary to adjust engaging bar 17 to the proper thickness,force engaging bar 12 into the grain immediately behind the door to apoint where its spur 22 engages door 6 adjacent thebottom edge thereof.Spur 23 of engaging bar 17 is now in contact with the outer face of thedoor adjacent the upper edge thereof. That portion of the connectingchain 9 extending from hook 10 to near the upper end of engaging bar 12is slack, and that portion extending from hook 10 to the outer end ofbody member 7 is tight. It is plain to see that an upward pull on hook10 will force both spurs 22 and 23 into the grain door 6, and an inwardthrust against the upper edge thereof will be imparted through engagingbar 17. As power is applied, the upper edge of door 6 will be :forcedthrough the arc of a circle having its center at the bottom edge of thedoor. Y The device of course should be affixed near one end of the doorto force it inwardly and upwardly before removing the opposite end.
